Embodiment Construction
[0025] Such as Figure 1-2 The structure of the matrix type liquid collection unit array rapid liquid discharge device is shown. The matrix type liquid collection unit array rapid liquid discharge device is mainly composed of a liquid discharge pipe 1, a vacuum pump 2, a liquid suction main pipe 4, a main pipe distributor 5, and a liquid suction branch pipe 3 , branch solenoid valve 7, branch distributor 9, branch suction pipe 10, bracket 8 and control unit 6 and so on. The discharge pipe 1 is connected to the outlet of the vacuum pump 2, and the inlet of the vacuum pump 2 is connected to the main pipe 4; Each port is connected to a liquid suction branch pipe 3, and the liquid flow in all liquid suction branch pipes 3 is converged to the liquid suction main pipe 4 through the main distributor 5; a branch solenoid valve 7 is connected in series on each liquid suction branch pipe 3 to control the liquid suction branch pipe. The on-off of the suction branch; the branch distribut...

The invention discloses a matrix type liquid collection unit array quick liquid discharge device and a liquid discharge method thereof used for spray mechanical fog distribution uniformity test bed. A liquid discharge pipe is connected with a flow-out port of a vacuum pump; a flow-in port of the vacuum pump is connected with a liquid suction main pipe; a main pipe distributor and a branch pipe distributor are both provided with a confluence port and a plurality of parallel branch ports; the confluence port of the main pipe distributor is connected with the liquid suction main pipe; each branch port of the main pipe distributor is connected with a liquid suction branch pipe; each liquid suction branch pipe is connected in series with a branch pipe electromagnetic valve; the confluence port of the branch pipe distributor is connected with a liquid suction branch pipe; each branch port of the branch pipe distributor is connected with a branch liquid suction pipe; all liquid suction branch pipes are arranged in a line and are inserted into corresponding liquid collection units; the branch pipe electromagnetic valve of a next liquid suction branch is switched every 1-5 seconds to discharge liquid; and thus, the requirements of two-dimensional latticed fine division at a fog drop deposition region are met, and more complete fog distribution information is provided.
Description
technical field [0001] The invention relates to a matrix-type liquid-collecting unit array quick-draining device, in particular to a matrix-type liquid-collecting unit array quick-draining device used for a spray machine fog volume distribution uniformity test bench, and belongs to the field of agricultural engineering test equipment and technology . Background technique [0002] The uniformity of fog volume distribution refers to the uniformity of the deposition and distribution of fog droplets on the target during the operation of the spray machine, and is an important indicator to measure the performance of the spray machine. The rapid and accurate detection of the uniformity of fog volume distribution is of great significance to improving the technical level of spraying machinery detection, optimizing the operating parameters of spraying machinery and improving the design level of spraying machinery.
